DRAWER CGNSTRUCTIONQ Application ledenuary 1G, 1922. Serial No. 529,541.

T 0 all w/om tf/nay concern: s

Be it known that L JUL-iris l'iiwlrorn a citizen ot' the `United il'atea and resident ot Chicago in thecounty ot @ook al l ot lllinois41 have invented certain ne till improvements in a Drawer (lon a. uctioiu ot which the 'following a specihcation.

lily inrention relates to a novel drawer ar rangement and particularly to certain details o'l" construction relating` thereto.

One of the principal objects ot my .inveir tion is torsimplity and lessen the cost ot drawer construction worlra particularly with reference to the drawers now commonly utilized by merchants tor containing their goods. lt has been `found desirable` particularly in the large cities where dust. and smoke are common, to carry goods or samples thereof in drawers so arranged as to be readily available to the salesmen in charge .of such goods. To that end l have provided a simple construction by which stacks ot drawers may be built up in a very economi cal manner and operated with a minimum ot exertion on the part of the user. .another object of the invention is to provide for a series of drawers arranged either in horizontal or vertical rows or both, the parts being so arranged as to effect a large economy or' space. This is an essential element in the use of devices of the kind referred to. ln order to effect this result the supporting' elements for the drawers are of the utmost simplicity and the minimum number of parts, Furthermore, in order to lessen the cost ot construction and installation the parts employed are such as are commonly produced and carried in stock, as for instance. rods, tlat bars and bolts. rl`hese1 together with the anti-friction elements. which may consist ot a standard forni oit roller bearing, constitute the sole trarne and supporting elements oit the drawer construction.

ln a stack of drawers constructed in the manner described, the skeleton traine work is not exposed to view, the drawer being; of such width as to wholly conceal the trarne when the drawers are closed.

A Jfurther object ot the invention is to provide a construction which has independent bearing support 'from the outer wal s trames or panels. Each staclr of drawers is supported on its own standards or uprights and therefore may be installed without regard to the wall against which the drawers are placed The inif'ention will he more readily understood by reference to the accompanying drawings. wherein,

o 8 is an enlarged sectional view through the anti-friction element;

l is an enlarged sectional view showthe meanseniployed tor effecting thev elevation et the drawers when in closed position in order to relieve the anti'friction element ot the weight thereof.

5 is a fragmentary view showing the torni of connection between the rear end of the drawer and its support;

Fig. 6 is "an enlarged sectional view through a inodilied orrn of anti-friction element, and,

Fig, 7 is an enlarged sectional view show a modified form oft connection between the drawer and anti-friction supporting element.

ln the drawings it will be seen that the drawer construction comprises a skeleton iframe including the vertical rods .10, and horizontal flat bars ll. rlhe rods are suitably anchored at their upper and lower ends, the upper ends being held in top closure or cap l2. The horizontal hars are maintained in proper spaced relation by means of spacing` sleeves i3, which are in etl'ect tubes through which the rods l0 extend. The rear end oi the drawer.v indicated at lll, is supported. only at its central portion? a project-ion l5 therefrom being' constructed tor sliding engagement with a longitudinally eX- ten'dingj rod 16. This rod, which is shown in the .torni ot'a bolt, extends trom the rear wall 17., to a deflected intermediate portion 18, ota horizontal. bar ll.l lt desiredyan anti-friction element in the itorin or" a roller or ball bearing? may be provided in place et the aperjt ire 19., in the projection l5, but l ced th at such provision is unnecesani coni/i sary and the elimination thereof serves to materially reduce the cost ot construction.

ln order to provide for ease ot movement of the drawers in opening and closing the same, I provide anti-friction elements, an eX- arnple of which is indicated in Fig. 3. ln that view l illustrate a ball bearing including upper and lower races 20., 2l, the balls 22 being` coniined therebetween. The parts constituting the races are axially apertured to accommodate the sleeve 13 therein. The bottom race rests upon one oi. the horizontal bars l1. rlhus it will be seen that the same ball bearing,` serves to support the respective sides or' two horizontally adjacent drawers. However, in order to eifect this advantage it is necessary that when the drawers are in their closed position the weight thereo't' should be lifted from the anti-friction elenient; other-wise the weight ot one drawer would prevent the i'ree operation ot the antifriction element in withdrawinff jacent drawer.. To that end l", provide, as shown in Fig. 4, a pair of inclined planes 23, one adjacent to each ot the side edges or' the drawer, these being adapted to cooperate with the horizontal bar il., and to effect the elevation of the drawer as it approaches its closed position. ln Fig. 3 one ot the drawers is shown in an elevated position while the other is shown resting upon the ball bearingr.

1n the construction shown in sie'. 6, l provide an anti-friction element in the form of a spool 2e, the upper and lower flanges 25,v 26, of which serve to guide and support the drawer. These spools are lil-rewise mounted upon the spacing sleeves 27 and operate in a manner similar to already .c escribed.

In the construction shown in Fig, fr', the anti-friction element is the same as that shown in Fig. 3. have, however, prol vided for lateral as well as vertical guiding' effect by grooving vthe lower corners oit the 'drawers as indicated `at 28. In other respects the construction so far as the rod cross bar 30 and spacing sleeves 3l is concerned, is identical with that heretofore described.

rIhe advantages of a construction such as thc adnally extending guiding and supporting bar, and a drawer supported at its sides on said anti-friction elements and at its inner end on said. bar.

2. ln drawer construction, the combination oic a 'keleton traine providing for vertical and horizontal rows of drawers, said frame including continuous vertical posts at the side of each vertical row ot drawers, anti-'triction devices mounted for rotation about a post as an axis.v and drawers sup-- ported at their sides on said anti-triction devices. f

f-g). in drawer construct-ion, the combinaltion ot a skeleton :traine providing for veral .and horizontal rows ot drawers, said Y.me including continuous vertical posts at the 'de of each vertical row of drawers, anti-'chretien devices mounted for rotation abouty a as an anis, drawers supported ai their sides on said anti-friction devices, and means lfor supporting the inner ends ot said drawers at a middle point.

d. ln drawer construction the combination oi skeleton frame providing' for vertical and horizontal rows ot drawers, said iframe including' continuous vertical posts at the side ot each vertical row of drawers, anti-'triction devices mounted tor rotation about a post as an axis, and drawers supported at their sides on said anti-friction devices, the same anti-'friction devices serving a support "tor two horizontally adjacent drawers.

. a drawer construction, the combinaframe providing for a horizontal row of drawers, said frame including; vertical posts, an antiwfriction device mounted lo; rotation on one/o' said posts and a portion oit the anti-friction device projecting into the plane or movement of two adjacent drawers.

6. ln a drawer construction, the combination. of a frame providing for a horizontal row ci drawers, said frame including vertical posts, an anti-friction device mounted tor rotation on one ot said posts and a portion the anti-friction device projecting into the plane of movement et two adjacent drawers, and means located at the bottom and near the center of the drawer opening for supporting and guiding; the rear end ot the drawer.
